IMPROVEMENT IN LOCKING-DEVICE FOR UMBRELLAS.

The Schedule-referred to inthese Letters Patent and making part of the name.

To (lll persons to u'hom these presents shall come.

Be it known that I, HORACE Tdtoeixs, of Boston, in the county ot' Suiiolk, .and State of Massachusetts, have invented anew and useful Lock for Umbrellas; and I do hereby declare that the same is fully described in the following specifications and accompanyin drawings, iignres, and references thereof.

Of the said drawings- Figure l denotes a side view oi' an umbrella-hanche, having my lock applied to it, showing the position of the lock when the umbrella is closed.

Figure 2 is a longitudinal section et' the same, showing the position ofthe lock when the umbrella is locked.

Figure 3 is a section, showing the position of the lockl when the umbrella is not locked.

Figure 4 is a side View ofthe key.

Similar letters refer to like parts in the dierent drawings.

A is the handle.

B, the runner.

C, the catch which holds the ruimer in place when the umbrella is closed. Y

D, the catch which. holds the runner in place when the umbrella is open. V

it -has long been a proverbial saying that there is no property in an umbrella7 owing to the propensity that many people have, when they require one, of ap-Y pwpriating the first one they can lay their hands on,

'To prevent this, (in a great n'uiasurc, at least, as few umbrellas are lost except when taken for immediatel nse,) I have originated the plan oi' locking them when left unguarded, so that they cannot be opened except by the owner, who has the key.

The nature of my invention consists in providing umbrellas with a lock, E, figs. 1,2, 3, and key F, iig. 4.

The lock E is made in the .form ol' a tube, .having llanges c b, which form the chamber c.

Inside this chamber is a conical spring, d, one end of which presses against the fla-nge a, in the lock E, the other end against the iiange c, on the runner B, figs. 2, 3.

This spring serves to keep the lock E back from the catch O, when the umbrella is closed, and not locked, as seen in figs. l, $5. i

When itis desircdto lock the umbrella, it is done by sliding the lock E down over the catch C, so that the-flange b passes down over the end of it, completely covering it, so it cannot be picked, and the spring f threes it up into the chainberc, as seen in tig. 2.

The catch C is made in two parts, for the purpose lof diversity, -and one end of cach piece is made with wards y, as seen in 2, 3, to suit the wards h in thc key E, iig. 4, and they cannottbe operated except by a key which exactly tits then'r.

Whenit is desired to unlock the umbrella, it is done by inserting the key F into the key-hole Ii, turning it, so as to depress the catch (l, thereby releasing the flange b and the runner B from the catch O, and the spring (l throws the lock E back into place, as seen in Afig. 1; then the mnbrella is ready to beopened.

The lock E may be made in various ways. The tube may-besubstituted by a bolt in the handle, to slide underneath the catch C, so that the catch cannot be depressed without irst sliding the bolt out from under it by means of a key.

This bolt may be made in one or more pieces, having 'ards to fit the wards in the key, and the catch C may be made ot one or more pieces ot'platc, or it may be made of wire, similar to the catch D; or thev lock may be made of a tuhe, as described, located on the handle below the runner, to slide up over-the catch when locked. But I prefer to make the lock so as to cover the catch Gto prevent it trombeing picked or broken when the umbrella is locked.

l. l claim the tube l), with or without the spring d, so arranged to slide over and enclose the catch C, when the umbrella is locked, and to slide back from the catch when it is unlocked, substantially as described.

-2. The arrangement ofthe runner B, the lock E, the catch O, the spring u., and key F.
